Description
Technical Field
The invention relates to the technical field of automatic cross shaft correction equipment, in particular to an automatic integral cross shaft correction device for a split cross shaft of a heavy truck.
Background
The current commonly used cross axle of the differential between heavy truck wheels is of a split structure and consists of a cross axle integral axle and two split axles perpendicular to the cross axle integral axle. The whole shaft of the cross shaft is a slender shaft, two waist grooves are arranged in the middle of the shaft length, are perpendicular to the axis and are opposite to each other, and are respectively used for being matched with the two split shafts. The whole cross shaft is subjected to bending deformation after carburization and quenching, and needs to be subjected to reverse bending pressure straightening treatment. The pressure straightening of the existing heavy truck split cross axle integral shaft after carburization and quenching is mainly carried out by a single pressure head press. During straightening, firstly, the whole shaft of the split cross shaft of the heavy truck is fixed, then a pressure head of a press is directly used for pressing the convex part of the shaft and applying pressure to the convex part until the bent whole shaft of the split cross shaft is reversely bent, and the split cross shaft rebounds to form a straight shaft after pressure relief. Because the middle part of the whole cross shaft is provided with two waist grooves which are opposite to each other, the waist grooves are weak parts of the shaft, the rigidity is low, and the capability of resisting bending deformation is weakest; when the pressure is applied by straightening, the pressure is concentrated when a press with a single pressure head straightens, so that most of the reverse bending deformation of the whole shaft is concentrated at the middle part with the weakest bending deformation resistance, and the middle part of the whole shaft of the split cross shaft is easy to break.
